I have restructured the thread to be more mathematically conclusive and to prove mathematically the original point brought up by beaslbob. I also extended the analogy in a way that I really like.

Now I made the equation much more user-friendly! Here are three easy ways that the equation can be used (check out the last one-it is my favorite) Here is the equation, simply plug in your values for everything but w and a. What you will end up with is a graph. The graph will show you what your...

Ammonia has been stable over the past couple of days. I have 2 ammonia test kits, so I am testing frequently (because why not?). I will need them again when I move the tank, but that will be a while. I haven't tested for anything else yet.

It's funny. This is a simple problem to understand, but the solution is incredibly complicated. I expected to spend a few minutes on this. Boy was I wrong. The thread is finally fixed.

I have this totally figured out. In fact I was editing the thread when my computer crashed. Are you kidding me? Later tonight I'll have this up. The equation is ugly. Here's a sneak peek.

Yellow watchman goby. Definitely in my top five favorites (yellow is my favorite color). That was a good decision on your part. Your lid should be fine, but others might suggest blocking the hole. At the same time, you want gas exchange though. A lot of hobbyists use mesh for covering. My...

I just realized that wolfram alpha decided my copy and paste tactics were no bueno. That in conjunction with the minor error I found is enough to scrap this thread and do a repost later (or at the very least fix edit it). I did this in haste and was not very clear or thorough. I will also try to...

I will begin by accrediting beaslbob for the original idea. His analogy involved galloping elephants, which were used as a general unit of measure. They can be easily replaced with other elements/molecules/levels in the aquarium. Specifically those that we wish to reach 0 (nitrates, phosphates...

I am going to start a new thread and discuss what is happening using a mathematical model.

I have the tendency to agree with Seth. If everything is introduced properly and the proper precautions are made, then it serves virtually no purpose. Of course, I wouldn't condemn someone for using one. In practice, yes your idea will work. EDIT: Yes, it kills algae spores. But only those that...

Quote: Originally Posted by SnakeBlitz33 Dude,... your tank is small. You don't need macroalgae or a scrubber to keep a clean tank. Water changes alone is good enough.... You're right. Thanks for the reassurance. It feels weird running this tank with such little filtration, that's all. I threw...

Okay, new question (and no making fun). Since macroalgae seems like an impossibility, how absolutely ridiculous would it be to run a little turf scrubber or in-the-stand refugium on this little tank? What about an upflow filter with some chaeto?
